PURPOSE:To mix thoroughly paints and to permit easy color changing of the paints by disposing a pair of spraying nozzles in an annular groove of an atomzing head and injecting a main material from one of said nozzles and a hardener from the other at the same instant. CONSTITUTION:Respective press feed pumps 16a, 16b are first operated and regulators 15a, 15b are so adjusted that the paints to be coated are supplied at the rates meeting the amt. to be coated in the case of mixing the main material in a main material tank 17a and the hardener in a hardener tank 17c at 2:1 ratio. The rotating speed of an atomizing head 3 is then increased and a negative high voltage is impressed on the head 3. When stop valves A, C are simultaneously opened, the main material and hardener are simultaneously supplied from the repsective corresponding ejection nozzles 7, 8 into an annular groove 5 and the two materials are thoroughly mixed and agitated to a paint by the high speed revolution of the head 3. The stop valves are changed and the nozzle 7, the groove 5, etc. are washed in the case of using a paint of another color.
